DALLAS (AP) — A fire alarm at a Dallas airport forced thousands of holiday travelers to leave their gates and gather at security checkpoints, but most flights were not delayed by the disruption.
Officials at Dallas Love Field say an air-conditioning unit overheated early Friday, generating smoke that triggered the alarm.
Firefighters determined within half an hour that there was no fire or threat, but the alarm required people to return to the check-in and lobby areas.
The resulting wait to go back through security was upward of 90 minutes.
Most flights were not delayed, but some passengers struggled to reach their gates in time because of the security backup.
